Customer's archive jobs would not complete after producing errors for several several mailboxes.  Retain was reporting AutoDiscover errors when logging into some of the mailboxes:

09:18:02,977 AutodiscoverFunctions - No EWSURL or ASURL in response request for []
09:18:02,977 AutodiscoverFunctions - This will mean we will fail to find an EWS service suitable for this user.
09:18:02,977 AutoDiscover - Not good. No good EWS URL returned... code=connectButNoUrl,payload=[null, -1]
09:18:02,977 ExchangeDredger - No Autodiscover/Endpoint found!
com.gwava.archive.exceptions.ExchangeAutodiscoverException: No Autodiscover/Endpoint found!


The customer had employed Active Directory's Certificate Mapping.   It involves PIV certificates that have to be mapped to each Active Directory account.  Essentially, they right-click on a user, select "name mappings", and remove or add a cert. For the problematic users, they removed the certificates and added another one.
